Understanding Periodicity and Bonding in the Periodic Table

What is the term used to describe elements that have properties of both metals and non-metals?

• Metalloids

• Noble gases

• Halogens

• Alkali metals

What is the primary reason metals can conduct electricity?

• Strong metallic bonds

• Delocalized electrons

• High melting points

• Presence of cations

Why do metals generally have high melting and boiling points?

• Because of strong electrostatic attraction between cations and delocalized electrons

• Because they are dense

• Due to their large atomic size

• Due to their ability to dissolve in water

Which metal in Period 2 has a stronger metallic bond, lithium or beryllium?

• Lithium

• Neither has a metallic bond

• Beryllium

• Both have the same strength

What typically happens when metals are added to water?

• They dissolve completely

• They react with water

• They form a gas

• They remain unchanged
